[Mesa-users] Error in make_co_wd test case (r24.08.1)

[Huaiyu Duan]

Hello,

I tried to run the make_co_wd test case in r24.08.1 but failed. I’m very new to MESA, and I don’t completely understand the error messages it generated. (See below for the last few lines of the output.) Here is my guess, though.

I had MESA set up as a systemwide package so that the students in my class can avoid all the technical issues of installation. I copied make_co_wd from the test_suite directory to my own scratch space and ran it there. But somehow MESA wanted to copy some of the stuff generated in during the run back to the main MESA directory which is forbidden.

Is my interpretation correct? If so, is there way to disable this behavior or is MESA not designed to be shared by many users who may run it simultaneously? Thank you!
